How far this bird wanders North in Burma has not yet been defined. It is found throughout peninsular Tenasserim, Siam and the Maly Peninsula.
Bingham found the nest of a Black-headed Yellow Bulbul in Tenasserim which must have been of this race. He writes:— “Common enough in the Thougyeen forests, affecting chiefly the neighbourhood of villages and clearings. The following is. a note of finding the nest and eggs I recorded in 1878 :—On the 14th April I happened to be putting up for the day in one of the abandoned Karen houses of the old village of Podeesakai at the foot of the Warmailoo Toung, a spur from the East watershed of the Meplay river. I had returned tired, from a search for bears, and was moving about among the ruined houses, between and among which a lot of jungle was already springing up, when, just as I passed a low bush about 3 feet high, out went one of the above¬mentioned birds ; of course the bush contained a nest, a remarkably neat-shaped affair, below and outside of fine twigs, then a layer of roots, above which was a lining of the stems of the flower of the “theckay” grass.”
Mackenzie describes a nest as “a shallow cup smaller than most Bulbuls’, of dried leaves, roots and moss-roots, lined with rather finer roots and grass ; a loosely put together but rather strong nest. External measurements 3.1/2 x 2.3/4 inches ; internal 2 x 1.3/4 inches. The nest was placed 10 feet up in some brambles on the bank of the river. Another nest was found containing three young birds on the 2nd of April, nearly fledged. This nest was built in a bush about 3 feet high. In the first nest, which was taken on the 27th March, there were two eggs only.” These nests were taken by Mackenzie in Tenasserim.
Mr, E. G. Herbert found this bird not uncommon in South¬-West Siam and took several nests. On one occasion, the 25th May, he took three nests, each containing two eggs, which he gave to me.
The eggs are like poorly-coloured eggs of the preceding bird and, as with them, none have blotches, the most one could call the markings being large freckles. In one pair of eggs there are distinct caps, the markings, more especially the secondary grey ones, almost coalescing at the larger end. In the other eggs the freckles are slightly more numerous at the larger ends but there are no indications of caps or rings.
Ten eggs average 21.6 x 15.6 mm. : maxima 22.3 x 15.4 and 22.1 x 16.1 mm. ; minima 21.0 x 16.0 and 21.1 x 15.0 mm.
It is interesting to see that this small series of eggs does corroborate the division of the species into two races on the ground of size, although it would not be safe to generalize on so small a number.
